First, uninstall NTFS-3G/Paragon if installed.Open Terminal.app (/Applications/Utilities/Terminal)Type "diskutil info /Volumes/volume_name" and copy the Volume UUID (bunch of numbers).Backup /etc/fstab if you have it, shouldn't be there in a default install.Type "sudo nano /etc/fstab".Type in "UUID=paste_the_uuid_here none ntfs rw" or "LABEL=volume_name none ntfs rw" (if you don't have UUID for the disk).Repeat for other NTFS partitions.Save the file (ctrl-x then y) enter and restart your system.

After reboot, NTFS partitions should natively have read and write support. This works in both 32 and 64-bit kernels. Support is quite good and fast, it even recognizes file attributes such as hidden files.
